One-Click option to replace all batteries in the system

It would be nice if there was one button a customer could click that would order ALL the batteries for their entire system vs having to go through and order them all individually.  Maybe it would allow you to order all of them and then would let you remove the ones you don't need (like the base station, etc.).  Our system is pretty large and the batteries are starting to fail at the same time.  For me it is a second home so I don't realize what has run out until I access the house.  I know I could look online, but I don't unless the alarm has been triggered.  If I could get all the batteries at once, I could bring them to the house and change them at once.  Just a suggestion.
